Clinical rabies in humans can be divided into five stages: incubation period, prodromal stage, acute neurological phase, coma and death (Bernard, 1984). The average incubation period of between 31 and 90 days has been reported, but it can be as short as 7 days, although it could be as long as 25 years (Shanker et al., 2012). Exposures through bites on richly innervated areas of the body like the face, neck, hand and, especially, finger-tips lead more frequently to clinical infection and a shorter incubation period. Bites that occur on the trunk or proximal portions of the limbs may take longer time, unless such exposures are in direct proximity to major nerve trunks (Yousaf et al.,
